Geometry 1B Course Test 13-What is the volume of a square pyramid with an 8 x 8 foot base and an
altitude of 6 feet?

C

Step-by-step explanation:

Volume of a pyramid = 1/3 x ( area of the base x height)

Base is a square

area of a square = length² = 8² = 64

Volume = 1/3(64 x 6) = 128 ft³

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
